I'm a QA Engineer with 4+ years of experience across different domains (fintech, e-commerce, SaaS, web3, AI, etc.) and platforms (web, mobile and desktop), helping product teams release with confidence rather than crossed fingers. I come in, learn your product properly, and build the kind of testing setup that actually holds up, structured test strategies, solid manual and automation testing, and clear communication with your developers so nothing important slips through.

I test like your users, not like your spec sheet. Real user journeys, real edge cases. 30–40% fewer post-launch bug reports for clients who've made the switch. 2. I catch the bug's automation walks right past. Exploratory testing finds permission gaps, UI breaks, and state bugs. Cutting support ticket volume by up to 35%. 3. Bug reports your devs can act on immediately. Every report includes repro steps, severity, environment, and evidence. ~40% faster resolution, no follow-up pings needed. 4. Automation built to last, not to hand off as a problem. Modular, documented regression suites with a flaky test rate under 2%. Your team can own and extend them without me. 5. You'll always know exactly where your product stands. Structured test summaries at every milestone, pass/fail rates, risk areas, and coverage gaps. No surprises at launch.

When your backend goes down, users leave and revenue stops. I make sure that doesn't happen. I'm a Node.js backend developer with four years building and stabilizing production APIs and microservices across Healthcare, FinTech, EdTech, and Real-Time platforms — industries where uptime and data integrity aren't optional. Results I've delivered: — Migrated a live MongoDB database to PostgreSQL with zero downtime and zero data loss, across a 50+ user production system — then rebuilt the backend logic to handle PostgreSQL natively where it had only ever run on MongoDB — Migrated a MySQL database on a live PWA to Supabase PostgreSQL with Row Level Security and proper schema versioning — eliminating data corruption bugs that were wiping user progress, streaks, and financial records on every deploy — Expanded and restructured a PostgreSQL microservices database to support unified authentication across multiple services — users can now sign up, log in, and manage their profile from one platform with one login What I build for clients: API development — High-performance RESTful and GraphQL APIs using Node.js, Express.js, and NestJS, designed to handle load and stay maintainable as your product grows. This is the kind of API work a reliable Node.js backend developer should own end to end. Microservices architecture — Modular, independently deployable services built for scale, with clean inter-service communication and separation of concerns baked in from the start. Database architecture — MongoDB and PostgreSQL schemas structured for speed and long-term integrity, including advanced indexing and query optimization (one recent project cut DB load by 40%+). Real-time systems — WebSockets, live messaging, and presence features built cleanly into your existing stack. Auth & security — JWT, RBAC, OTP flows, and session management done properly from day one. Infrastructure & deployment — Docker, CI/CD pipelines, and automated monitoring so you're never caught off guard. Third-party integrations — Payment gateways, Twilio, and external APIs connected without future maintenance debt. 🧩 Real-World Solutions I've Built as a Node.js Backend Developer: 🏥 Healthcare Data Pipeline Built a Node.js backend processing 1,000+ patient records daily across a distributed system — with zero data loss, role-based access control, and HIPAA-aligned data handling built in from day one. 🏫 Multi-School Platform Backend Architected a modular Node.js microservices backend for EduConnect, serving 10+ schools with complex role hierarchies, tenant isolation, and data scaling — all without touching live service uptime. 🆘 Real-Time Crisis Support API Built the backend for Safe Anchor — a real-time victim support platform using Node.js, WebSockets, and optimized REST APIs, with encrypted communications and secure data handling under strict compliance requirements. ⚡ API Performance Overhaul Diagnosed and resolved bottlenecks across a production API layer — cutting response times by 45% through query restructuring, caching strategy, and connection pool tuning on PostgreSQL. 🗄️ Database Migration & Stability Migrated a live MySQL database on an active PWA to Supabase PostgreSQL — eliminating data corruption bugs wiping user progress and financial records on every deploy, with Row Level Security and schema versioning built in. ☁️ Zero-Downtime MongoDB to PostgreSQL Migration Migrated a live MongoDB database to PostgreSQL across a 50+ user production system with zero downtime and zero data loss — then rebuilt the backend logic to handle PostgreSQL natively from the ground up. If you need a backend that handles load, protects your data, and gives your product a solid foundation that lasts — let's talk to a Node.js backend developer who has done it in production.
